The article is devoted to the social mechanism of Lyons uprising in 1793. Analyzing the protocols of town and departmental councils as well as other sources, the author discovers the sequence of events because of which Lyon came into confrontation with Paris. The anti-Jacobin uprising seems as a result of complex combination of various factors such as the extremist actions of Lyon radicals, conflict of various branches of local government, the inconsistency of the Convention politics and the confluence of circumstances. The author refutes the widespread opinion that the Lyon uprising was royalist.
